Famously, she's focused a lot of her infrastructure work on expansion of rail. Including the 5.6 trillion peso Plan México and 3,000 new km of passenger train lines. She's also remodeling the Mexico City airport, modernizing and repairing 4,000 km of roads, and pushed the National Hospital Infrastructure Plan that will fund massive expansions of three major hospital systems. Also half of the infrastructure budget is allocated to energy infrastructure. Specifically to fund her massive clean energy transition. 70% of new energy is to come from renewables.

What other infrastructure do you have in mind?

Not to make a weak appeal to authority but have you spent much time in Mexico and much time speaking with locals? Those initiative are widely viewed as either failures, DOA, or political chips to appeal to the Morena base (which even then fails).

Once more, the "remodeling" of the Mexico City airport is a historic failure by the previous and current administration. A new airport was being built, funded solely by private money and the previous administration made a non-binding public poll on whether to cancel it because of baseless corruption accusations. That was 8 years ago, and as it turns out, Mexico City desperately needed a new airport anyways. So the Army took a military base and expanded it to build a toy airport far away, which no one uses, so they had to pour money into the old, aging airport. Renewables is also a smoke screen, last administration spent 0 on the energy infra and now that's why we face blackouts every other day.

Something that fits to a poor struggling country, not some upper crust infra renewal.

Poor people need rail, busses, cars and the cheapest possible power. If the government does not provide the cartels are more then ready to do its job to placate the citizens.
